Add new port graphics/libbpg:
BPG (Better Portable Graphics) is a new image format. Its purpose is to
replace the JPEG image format when quality or file size is an issue. Its
main advantages are:
- High compression ratio. Files are much smaller than JPEG for similar quality.
- Supported by most Web browsers with a small Javascript decoder (gzipped size: 56 KB).
- Based on a subset of the HEVC open video compression standard.
- Supports the same chroma formats as JPEG (grayscale, YCbCr 4:2:0, 4:2:2, 4:4:4) to reduce the losses during the conversion. An alpha channel is supported. The RGB, YCgCo and CMYK color spaces are also supported.
- Native support of 8 to 14 bits per channel for a higher dynamic range.
- Lossless compression is supported.
- Various metadata (such as EXIF, ICC profile, XMP) can be included.
- Animation support.
